copper sulfate

Chalky blue chemical powder

Copper sulfate is a blue crystalline compound used in agriculture as a fungicide and algaecide, in electroplating, and in chemistry demonstrations.

It appears in products that kill algae in swimming pools and treat plant diseases.

The vivid blue color makes it memorable in high school chemistry labs: We grew copper sulfate crystals for the science fair.
